Lichen removal
 
I have lichen and mold on my asphalt tile roof that is about 1000 sq ft.(roof is about 15 yrs old) What is the typical charge per sq ft for a cleaning service to remove this material.

Go to web sites listed on the right side of this forum, e.g.,

I think copper powder or Cu salts will stop moss growth.
